Why won’t the ring jump?
I’m a teacher, I remember doing this demo successfully during my studies. But now when I try the setup I remember it doesn’t work. Does anyone have any insights why it isn’t moving? When I turn it on there’s no movement at all. Not even the little jump you get when trying DC.
